T0 allewhom it may concern: Be it known that 1, Farmers T. JOHNSON,

" acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and 'useful Improvement .in Driers, of which the y dust, or any suitable filtering orsc 'een ng following is a specification.

My invention [relates to improvements in heaters and driers, and particularly to, an.

easily constructed, simple, knock-down drier, which may be used for drying clothes.

, Among the purp'osesofmy invention are the provision of sucha drier, which will be cheap,eflicient, and compact, and into which the clothes maybe easily placed; Another object is to provide such-a drier in which a; high degree of heat may be used without. scorching orotherwise damaging theclothes therein dried. Another object is to provide Another object is to provide a drier of which many uses may be made,- and my drier is adapted for use not only as a clothes drier,

but as a core drier, an enameling'ove-n or a heater. pOther ob ects-of my jlllVGHtlOl'l will appear from time to time in the course of the specifications. 1

I illustrate my invention more or less diagrammatically in the accompanying draw-',,

ings, wherein t Figure 1 is'av front elevation with parts broken away; i 'Figure 2 'isa section at 2..2 of Figure 1 Figure 3 is a section at 3-3 of Figure 1;

' Figure 4c is asection at H of Figure 1. Like .parts' are indicated by like. symbols throughout the specification and; drawings.

A is a front wallxof 'thefheater, which'is provided .with any suitable door frames, A,

The hook B on the upper side of the door frame is adapted to be engaged by a rod B,

pivoted as aIt'B' on one of the door'el'ements and loosely confined by the straps or loops- B B"; i The back of the drierina-y be" formed by a simple sheet or surface C, of metal like the rest of the drier. The sides are preferably:

doubled, the outer elements O, C serving as fines and the inner freely perforatedelements C (3, allowing free access of to a drier with a minimum of moving partswith hinges A on which are swung door elements, each comprising a front face A ,:and a rear face A, spacedaway therefrom. The

and from the interior of the drier. The member C isopen at the bottom and closed at the top, the inlet C serving as an air inlet. [tniay be direct from the. rooinasshown,

to or the airmay be taken fromv some outside] sourcespwherc it will notbe polluted by a I means,-not here shown, maybe used. 1 The rneinberC is closedat the b0tt0m,.but open at the-,top,,as at (1, as an outlet forthe moist clothing being drawn thereagainst.

The members C Cflarefurther provided with a plurality of transverse bars I) which are slotted or notched, to receivelthe trans? verse rods D the notches and rods being staggered,,there be-ingthree at one level, two

at-the next and three at the next, shown inFigure3. I Adjacent thebottomof the heating. casing is anangle iron shelf E, which surrounds lthe 1111101101. of the entire drier. Removably Somewhat above this pan.:is supported a supported thereby is the plate or l'pan E, having an upturned peripheral rim E 'which'fit in the straps F mounted 'onfthe heater walls. The screen and bars are both removable.

' Ben'eaththe' plate E are depending straps G,,G, upon which .is mounted a perforated support ng I,

gas-pipe'o'r burner G This pipe is bent,

and the outer end thereof penetrates as at G through the wall of the heater casing, and is provided with a stop cock, as alt-G G is lightinghole, having. alcove'r G and G is any suitable observationpeep hole,-pi1ef-.

.erably covered with mica. The entire structuremay be supported out of con-tactwith t-hefloor, as for example, by the supports G preferably integral with the frame ofthe entire'structure. v v

It; will be evidentthat'while I have shown a working; device and one which in use, yet

I do notineaii to be limited to the details shown, and many variations might be made in thenumber, 'siz e, shape and disposition of parts withoutidepai ting from the spirit of my invention. wish-therefore, that the drawings, and descriptions be taken as in large sense'diagrammatic.

The use and operation of my invention are as follows: I provide a simple rectan gular casing with a thin bottom compartment, having a heater within it, preferably a simple gas pipe burner. The gas may be turned oil or on from outside and a peep hole is provided to see whether or not it is burning properly. It may be lighted from the outside through the hole G, but when not open that hole is closed and there is no escape or waste of the heated air. The pan or plate over the heating element is removable for cleaning and it has above it a removable screen which protects the clothes from singeing contact with the heated plate. A drying current of air is admitted at the bottom of one side of the drier and is dis-- tributed by a side flue along the whole de vice, some ofit being sent through the heating compartment and the rest of it being supplied to the interior of the drier through a plurality of perforations, being spaced in rows along the sides of the casing. This air passes throughthe interior of the drier and out through the other side and up the flue shown at the right of Figure 1. The escape of the heated air through the perforations in the plate C adjacent the ends of the covering plate, insures constant draft through the drier and dry air is constantly drawn therethrough. The heater keeps-the entire interior of the drier and the air which passes through it at a high temperature, and the result is a ver quick drying, the heated moist air passing constantly up the flue C and being replaced with dry air, which is constantly heated as it passes among the articles to be dried. The doors are of a broad swinging type and allow a maximum access to thein'terior, but the escape of the heated air is minimized by stopping the doors midway the height of the drier. \Vhile they are opened, the opening may be par'tially' screened, as for example by a sheet. The goods to be dried are then inserted and laid over the supporting bars. As the bars are staggered, the articles hung on one row hang between the bars of the row next below. The bars may be removed for convenience of access to the rear bars and the size of the doors and the drier is such that all the bars are easily accessible to the operator. The opposed lips of the two door leaves are inclined to each other in order to make a tight contact and partly to provide a type oi door which may be easily closed and which has no tightlitting parts to jam; Furthermore, there is a minimum risk of damaging any clothes which may be gripped between the broad plate lips or bearing surfaces of the two leaves. The swinging latch shown is easy toopen and easy to close. This door may be opened and closed with a minimum of time and effort to minimize the escape of heated air or the entrance of cold air, which might delay the drying operation.

I claim: I

1. A drier comprising a clothes containing chamber, a heating chamber separate therefrom and directly therebeneath, a partition separating them, and a protecting screen spaced above said partition.

2. In a drier, a clothes containing chamber and a heating chamber and a partition separating them, and heating means supported beneath said partition, and a protecting screen spaced above said partition.-

8. In a drier, a clothes containing chamher and a heating chamber and a, partition separating them. and heating means supported beneath said partition, and a protecting screen spaced above said partition, said heating chamber and means being entirely inclosed and an observation Window therefor.

4. A drier comprising a drying chamber, a heating chamber separate therefrom, a re movable partition separating them, and a protecting screen spaced above such partition.

5. A drier comprising a clothes containing chamber, a separate heating chamber therebeneath, a plurality of removable clothes supporting elements within said clothes chamber, and a plurality of transverse shelve's adapted to support them, a

plurality being mounted on each shelf,- the" supports of each shelf being staggered in relation to those on the adjacent shelves, the vertical distance between the supports and the transverse shelves being substantially less than the average length or the articles of clothing normally supported thereby.

6; A drier COHlPl'lSlHg a clothes containing chambe and a heating chamber therebeneath, an air inlet flue at one side of the drier,- an air outlet flue atthe other side, and a plurality of air passages between said fines and the interior of the drier, said flues extending substantially from top to bottom of the heating chamber, at each side thereof.

7. A drier comprising a clothes containing chamber and a heating chamber therebeneath, a door in the upper portion of the clothes containing chamber, and a plurality of clothes su 'iporting burs extending across said clothes containing cha'i'nber adjacent said door, the bottom of said door being substantially above the bottom of said clothes containing chamber;
